These are the kind of questions/concerns/whatnot I was hoping to solicit.
Simple answer: on these servers, no. I don't have the time and patience
to tweak them a lot. Possibly I will make some 64-bit chroots then in the
future if I feel a specific program will benefit from it - but other than
that, it sounds like it's 32bit for me.

i was able to compile my own 2.6.5 kernel on my biarch test box... but
trying to compile some other stuff was a mess because the different
package managers had installed some libraries in different places.

Something that works.
